The resulting images were examined by the hospital's neuroradiologists, neurologists and neurosurgeons who immediately appreciated their value. There was international media interest and hundreds of clinicians visited the hospital to see the new scanner. Hounsfield shared the 1979 Nobel Prize in Physiology or Medicine with the physicist Allan M. Cormack “for the development of computer assisted tomography”.
The first edition of the World Health Organization Classification of Tumors of the Central Nervous System was published in 1979 and took almost a decade to complete.
